This is a Continuation of application Ser. No. 10/722,398, filed Nov.28, 2003.

BACKGROUND OF THE INVENTION

The invention refers to a variable background for photographic pictures.

Photograph desks for forming a background for special photographicpictures are known. These are photograph desks which have a stablestand, respectively a frame, between which a foil, respectively a slab,is arranged fixedly. It is also known to design these photographic desksin such a way that they can be dismantled.

All solutions which are known so far for this problem are photographicdesks which cannot be changed in their angle positions. This goes alsofor photographic desks which are designed to be dismantled for transportand storing.

If a background as homogenous as possible has to be created, for exampleto photograph a comparatively large object, then this is either notachieved at all or only with considerable (time) effort with the knownphotographic desk.

From the German specification DE 37 28 668 A 1 a variable background forclose shots is known which can also be allocated to the solutions of thestate of the art described before. The solution described here comprisesa basic slab on which a frame is screwed. Basic slab and frame here arearranged rectangular to each other. A girder with clamping devices forattaching a background cardboard is arranged movably on the frame. Asimilar clamping device is provided on the front edge of the basic framein order to clamp on this background cardboard as well. By means ofadjusting the girder on the frame the radius of the background cardboardcan also be altered. In the frame three rollers are provided furthermoreon which tarpaulins made of textile materials or similar materials indifferent colours can be arranged. If required one of the tarpaulins canbe uncoiled and also be fastened to the clamping device of the basicslab. However, this produces a comparatively unstable form of the fabricwhich may have negative influence on the photographs, for examplebecause of wind movements or the like. If more stable material is usedthe mouldability is limited to very few embodiments. The device also isaltogether very complicated and has to be dismantled for transportationwhich makes the whole matter very time consuming and inflexible. Thisvariable background may be suited for studio shots. For the flexibleuse, for example at the customer's, this apparatus is too unwieldy.Furthermore the forms of the flexible background which can be set by thedevice are very limited so that the pictures which are possible by meansof that do not guarantee an optimum background design with verydifferent forms, either.

The dismantling, respective the mounting, of the solutions for thephotographic desks known from the state of the art is altogether verytime consuming. This is in particular a disadvantage as shots like thatnowadays have to be produced within a very short time, for example afterthe telephone call of the customer, at the customer's. For that purposeit is necessary to take the complete photo equipment inclusively thedismantled photograph desks to the customer's and to produce there thecorresponding photographs of products, construction parts and so on. Themounting, respectively the dismantling of the photograph desks takeshere a lot of time so that this slows down the whole procedure. Thedemand for very fast results does not allow anymore such a loss of time.The present systems are so inflexible that for very different shots, forexample, even different photograph desks are needed in order to be ableto realise different forms of design.

BRIEF SUMMARY OF THE INVENTION

Coming from the state of the art described above it is an object of theinvention to create a solution that provides a background forphotographic pictures as flexible as possible, which can be alsotransported easily.

According to the invention this object of the invention is solved by avariable background for photographic pictures which comprises a flexiblebasic body which supports the object which has to be photographed,wherein the flexible basic body has at least one adjustment device formodifying the shape of the basic body. The flexible basic body can beformed here by a translucent, colourless and/or coloured plastic foil ormetal foil. Of course the basic body can also be formed from a white orcoloured cardboard which is sufficiently stiff. By means of thiscombination of this flexible basic body with an adjustment device formodifying the shape of the basic body, it is easily possible, by meansof such a simple foil combined with an adjustment device, to put thisfoil and adjustment device in addition to the camera equipment's, whichare necessary, into the trunk of a car and to go to the customer inorder to produce the required shots. In addition to the saved time forestablishing the background for photographic pictures there is also theadvantage that by means of the foil and the adjustment device thepossibility is presented to design very different angles up to theS-form for a variable background by means of this simple foil. By meansof that very high requirements concerning the background can be met withvery simple and economic solutions. By means of the high variabilityalso large objects can be photographed in a simple way. The inventionrealises in a way which is simple to mount the establishing of a “small”photo studio which is even suited for professional work at thecustomer's in a short period of time.

An opportunity for the realisation of the adjustment device is given,for example, by the fact that on the sides of the flexible basic bodyopenings are arranged which can be designed as circular or elongatedholes through which, for example, a cord string may be drawn. This cordstring here is guided alternately through the openings. By means of thecord string the foil may be drawn into different shapes by tensioning.These cord strings have fastening means which make a tensioning in veryangle positions possible. If, for example, two cord strings withdifferent fastening means on both sides are used, also a tensioning inS-shape is possible. The fastening means here may be indicated byclamps, knots in the cord string, by buttons with clamping devices, pinswhich are arranged movably on the cord string or the like.

Therefore by means of the solution according to the invention of avariable background a background is created which can be mounted quicklyand which is flexibly suitable for all possible and different shootingtechniques.

According to an advantageous development of the variable backgroundaccording to the invention the flexible basic body is formed by atranslucent, colourless and/or coloured foil.

The variable background is also characterised by the fact that theflexible basic body has such a stiffness that it can take differentshapes, however, keeps an even surface, if the shape is changed. Forthat purpose, for example, plastic foils are suited, which may beflexible, however, sufficiently stiff in order to carry out bendings andangles without any problems. However, the surface of the foil remainseven, in order to avoid shade edges. After the releasing of theadjustment device, respectively the fixing, the foil returns into itsown original shape on its own.

According to an advantageous development of the invention therefore theflexible basic body is formed by a plastic foil, paper, respectivelycardboard, or even by a flexible metal foil.

Another aspect is given by the fact that the adjustment device isindicated by openings obtained at least on one side of the flexiblebasic body by means of punchings, through which a string, a rope, afiber or the like is guided alternately, respectively S-like, wherein atleast one end of the string can be fixed by means of a fixing means. Itis sufficient if at least one fixing means for fixing the tension of thestring is provided, when here at least one side of the string is linkedfixedly with the variable background, respectively the sliding of thestring through the openings is prevented by means of a knot. The fixingmeans may also be indicated for example by means of fixing screws whichare shaped cylinder-like with a boring for the string. Here a screw canbe screwed into the cylinder in such a way that it clamps the stringguided through the boring by means of clamping it with the screw. Ofcourse, in the same way fixing means which operate with spring force canbe used. Furthermore, naturally, it is possible to use screws, pins orthe like, which lead to a fixing only by winding or knotting them withthe string.

According to a convenient development the variable background ischaracterised by the fact that at least on one of the cross sides of theflexible basic body reinforcements are provided.

These reinforcements reach that the flexible basic body does not sagwhen photo objects are put on when these have a certain weight.

It has also been found to be an advantage when the reinforcements areindicated by metal bows, plastic reinforcements or the like. It is, forexample, sufficient, if the reinforcements are shaped by an angle of thefoil at the ends of the flexible basic body. With even heavier photoobjects it may be necessary then to indicate these reinforcements bymeans of metal bows or plastic bows or strips. These strips or metalbows are designed here in such a way that they are fastened either tothe flexible basic body or the shots are taken even without thesereinforcements if a reinforcing is not necessary.

According to a development of the solution according to the invention itis provided that the flexible basic body can be brought into the angledposition by means of the adjustment device, wherein the angle can bechosen freely and, according to the respective photographic picture,respectively the photographic technique, can be modified freely. Thiscan simply be solved by means of the simplest form of the adjustmentdevice, namely by a cord string guided through the openings, if bothends of the cord string are provided with fixing means by means of whichthe tension can be modified, or even, if only one fixing means isprovided, and the other end of the cord string is, for example, arrangedfixedly at the flexible basic body.

In a development of the variable background at least two or moreangulations of the flexible basic body are provided. This is achieved,for example, through two adjustment devices, respectively two cordstrings, with fixing means on the basic body on at least one side ofthis basic body. More constant angle shapes can be reached by arrangingthe cord strings on both sides of the flexible basic body and bytensioning them equally.

The arrangement of the openings here can be carried out with regulardistances only in pairs or also irregularly. This depends in theindividual case from the shapes of the variable basic body which has tobe designed.

According to a development of the variable background it is providedthat the basic body has such a stiffness that it forms a tunnel whenopposing sides of it are linked and tensioned by means of the adjustmentdevice. By means of that also in a very simple way shots with thedesired tunnel effect can be realised.

A development of the variable background provides that by rolling of thebasic body itself and then tensioning of the variable basic body bymeans of the adjustment device, respectively of another fixing means, ittakes the shape of a tent. This other fixing means may be realised, forexample, through a Velcro fastener, which is arranged in the shape of adot on both sides of the variable basic body. It is also possible toprovide just openings on certain points through which then a fixingmeans, for example a screw, rivet or the like is guided in order to fixit. Of course, also a snap fastener is suitable for that purpose.

According to a convenient development of the variable background it isprovided that by means of rolling of the basic body itself and followingtensioning by means of the adjustment device it forms the shape of atube.

A development of the variable background provides that the basic body,as described before, then is brought into the shape of a cone,respectively a truncated cone. When this form has been reached the basicbody is fixed again at the provided points.

The invention is characterised by the fact that on the longitudinalsides of the basic body fastening devices are provided by means of whichthe basic body can be fastened to a support or the like. By means ofsuch a solution it is then possible that the variable background can befastened to a desk, frame or the like so that an unintended shifting,respectively moving, is more difficult then. As fastening devices in thevariant described before screws, rivets, paper clips, clamps or the likeare suitable.

According to an advantageous development of the invention the fasteningdevice is indicated by means of a Velcro fastener, snap fasteners, zipfastener or the like.

One development of the variable background is characterised by the factthat the basic body is designed in such a way that it can be put on aframe, in particularly fixedly. By means of such a solution then aphotograph desk can be realised which is characterised against the stateof the art by the fact that the basic body is designed flexibly andthrough that any form for special photographic pictures, as describedabove, can be realised. The frame can be here already designed as adesk, however, it is sufficient if in the simplest form first of all asimple frame is provided on which then the basic body can be putfixedly.

Another aspect of the variable background according to the invention isgiven by the fact that the frame is designed as a frame consisting of atleast three parts wherein the single parts can be connected to eachother. In this way then the form of a desk, chair or the like can becombined through the single frame parts.

A development of the variable background according to the invention ischaracterised by the fact that the frame parts can be connected to eachother by means of inserted connectors. It is a particular advantage hereif inserted connectors are available in different angles.

A development of the variable background provides that the frame partscan be connected to each other by means of joints which can be fixed.Also, by means of these joints, any desired angle can be set. Becausethe flexible basic body can be fixed, for example, to the frame, it ispossible to adjust the flexible basic body to the shape of the framealready without the adjustment device.

It has also been found to be an advantage if the frame, respectively theframe parts, have been manufactured from flexible profiles, inparticular tubes, which can be moulded universally, they are, however,are designed that they are after the moulding sufficiently stable tokeep the chosen form of the frame, respectively the frame parts.Flexible tubes of this kind are, for example, known in the lamptechnique or also as tripods which can be changed universally.

According to a further development of the variable background it isprovided that the flexible profiles are arranged as adjustment device onthe flexible basic body. It is, for example, provided that on theflexible basic body fastening devices, as described above, are arrangedwhich are located correspondingly also to that on the flexible profiles.By means of the connection of the flexible basic body via the fasteningdevice it is possible then to use these flexible profiles simultaneouslyas adjustment device for the flexible basic body. This results in alarge number of design possibilities for the variable background.

A development of the variable background according to the inventionprovides that the frame parts are linked with joints. These joints herecan be fixed and are equipped with catchings. By means of that verydifferent angles of the frame, respectively the frame parts to eachother, can be set quickly.

A development of the solution according to the invention provides thatat least a part of the taking region is formed by an opaque slab, whichpreferably can be also mounted on, respectively at, the frame.Advantageously, of course, also the flexible basic body can be mountedto this slab by means of accordingly provided fastening devices.

It has also been found to be an advantage if a light source can bearranged below, respectively before or behind, the variable background.By means of that again very different photographic techniques can berealised.

According to the invention it has also been found that it is convenientif a repro column is provided which can be fastened to the frame. Thisrepro column can be fastened universally to very different points of theframe or even outside this range, for example, to a desk. Light sourcesor even a photo camera, respectively a video camera, can be fastenedthemselves to this repro column.

The variable background according to the invention is characterisedaccording to a development by the fact that a transport device isprovided where all parts of the variable background are stored in such away that they are, during the transport, fixed in it and, in particular,protected against concussions and damages.

Another aspect of the invention is indicated by a flexible photographdesk, comprising a flexible basic body according to one or more of theembodiments of the invention described before, and a frame which theflexible basic body can be put on and in particularly be fastened to. Bymeans of such a solution then always a universal and flexible desk isavailable the kind of which is not known so far in the state of the art.This photograph desk can be, without any problems and in a very shortperiod of time, dismantled and therefore stored in any car withoutspecial transport apparatus.

The invention also provides a system for a variable backgroundcomprising at least one flexible basic body according to one or more ofthe embodiments described above, at least one frame as described aboveand at least one opaque slab, one or more light sources, one or morerepro columns and at least one transport device. By means of providing acertain system out of the variants mentioned, according to therespective demands of the customer, for each special application thenecessary material can be assembled and this may be carried out on veryshort notice so that very different demands can also be met on a shortnotice.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 a shows a variable background according to the invention in itssimplest embodiment. Here this variable background comprises a flexiblebasic body 1. The object which has to be photographed has to be put onthis flexible basic body. The flexible basic body here can be formed,for example, by a translucent, colourless and/or coloured plastic foil,respectively metal foil. The flexible basic body can also be formed by awhite or coloured cardboard which is sufficiently stiff. On the sides ofthe flexible basic body 1 the adjustment device 3 is arranged.

The adjustment device 3 is formed by a string 3/1, the fixing means 3/2as well as the openings 3/3. These are arranged in regular distances onthe basic body, as well as in pairs, respectively in differentdistances. For example, the openings 3/3 are the results of punching.Suitable as fixing means 3/2 are in particular clamps through which thestring 3/1 is guided and the clamp is held in the fixed position bymeans of spring power. If the tension of the string 3/1 has to bechanged the fixing means 3/2 is released and then again fixed in the newdesired position, and in the simplest form a fixing can be achieved, forexample, also by means of a knot in the cord string. The flexible basicbody 1 has such a stiffness that it forms an even surface and is notundulated and even through tensioning by means of the adjustment device3 keeps an even surface at the bendings. This is reached, for example,by means if a suitable thickness of the foil, respectively thecardboard. The string 3/1 which also may be a rope, a fiber or the like,is guided in S-shape through the openings 3/3. Preferably the string 3/1is fastened to one end of the flexible basic body 1, respectively fixed,and can be fixed to the other side (in FIG. 1 a on the right hand side)by means of a fixing means.

FIG. 1 b shows a development of the variable background according to theinvention. Here the flexible basic body 1 has, in addition to thealready described features, reinforcements 2 on the left hand and theright hand side each which are fixedly as well as releasably linked withthe flexible basic body. These reinforcements 2 are intended to preventa sagging of the flexible basic body 1 when the object which has to bephotographed has a corresponding weight. In the drawing according toFIG. 1 b on the longitudinal sides of the flexible basic body 1fastening devices are arranged by means of which the flexible basic bodycan be fastened to a support, for example a frame or a desk. By means ofthat, for example, an unintended shifting, respectively moving, is mademore difficult, respectively prevented altogether. The fastening means 4can be indicated for example by a Velcro fastener, snap fasteners, zipfasteners or the like. The reinforcements 2 on the cross sides of theflexible basic body 1 are indicated preferably by metal bows, plasticreinforcements or simple angles of the foil itself. The reinforcements 2are designed alternatively fixedly or removable. The embodiment of theflexible basic body 1 according to FIG. 1 b shows that in this drawingtwo strings 3/1 are arranged on each side of the flexible basic body sothat by means of the adjustment device 3 there is the possibility toinfluence the basic body with different tensions, realising verydifferent shapes.

The FIG. 2 a shows a flexible basic body 1 which has been tensioned bymeans of the adjustment device 3 in an angled form. This is here arectangular tensioning of the basic body 1. However, this may be easilymodified by changing the tension. By means of that easily also anotherangle shape deviating form a right angle can be reached. With thereference number 2 the reinforcements are indicated again which are, forexample, in this drawing designed in such a way that they can beinserted.

FIG. 2 b shows another embodiment for the angle possibilities of theflexible basic body 1. By means of tensioning the flexible basic body 1on two points with two independently working adjustment devices 3 heretwo angles have been formed which can be realised for special photopictures.

FIG. 2 c shows a tensioning of the flexible basic body 1 in tunnelshape. This may be achieved, for example, by guiding a string 3/1 onboth sides through the flexible basic body, respectively the openings3/3 located there. On both sides then in the drawing according to FIG. 2c the flexible basic body is fixed by means of the fixing means 3/2 sothat the tunnel shape remains. The flexible basic body can be designed,according to a very preferred variant, also as a narrow strip which istensioned on both sides by means of the string 3/1 in such a way thatthe already mentioned tunnel shape appears. This tunnel shape then canbe positioned upright like a tunnel. However, it is also possible to putthe tunnel formed in such a way on its side surfaces so that asemicircular background is produced between which, for example, theobject which has to be photographed can be located. Here it isfurthermore an advantage if a lighting device is positioned, for examplein a carrier particularly provided for that purpose, near the backgroundin order to reach special light effects. If a self-standing stand forthe light device is chosen and the upper part of the light source itselfis designed that it can be angled, very different light effects by meansof the variant described above can be reached in the design of the basicbody. The fixing of the string 3/1 can be carried out by knotting or bythe already described fixing means, respectively fastening means. Bymeans of different tension different bow shapes can be produced. Such asolution can be realised very simply and causes comparatively low costs.The material of the flexible basic body can be produced here from atranslucent foil, a white foil or even from other suited materials likemetal foils which can be bent flexibly.

For very special photographic pictures the tent form of the flexiblebasic body 1 is suited, as it is shown in FIG. 2 d. The tent body isbrought into the desired tent form by means of rolling the flexiblebasic body. By means of the fixing means 3/1, respectively otherprovided fixing means, this form can be stabilised so that during thetaking no changes of the undesired kind occur. Of course, by means ofrolling the basic body 1 with other angles, respectively tensions, alsothe form of a truncated cone can be produced.

FIG. 3 shows a development of the solution according to the invention.This is a flexible basic body 1 which is arranged on a frame 5consisting of frame parts 5/1, 5/2 and 5/3.

At the connection points of the single frame parts 5/1, 5/2,respectively 5/3, joints 7 are arranged. These joints are designedpreferably in such a way that they can be fixed. In particular they maybe fixed in such a way that different angle positions can be realised ina very short period of time. On the frame part 5/2 an opaque slab isarranged as it is already used normally for photographic pictures. Theopaque slab 8 is supported plainly by the frame part 5/2 and canpreferably be fixed. The combination of an opaque slab 8 and a flexiblebasic body 1 increases the possibilities for special photographicpictures. With the reference number 4 in the drawing according to FIG. 3the fastening device is indicated schematically.

FIG. 4 shows a photograph desk which has been created by the combinationof the single frame parts 5/1, 5/2, 5/3 via inserted connectors 6. Withthe reference number 8 again the opaque slab is indicated on which aflexible basic body is arranged in this drawing in the form of a tunnel.Below the frame part 5/2 a light device 9 is arranged by means of whichspecial light effects can be realised from below. With the referencenumber 10 a repro column is indicated on which also a light, a mirror orother completion parts for photographic pictures may be arranged. Ofcourse, it is also possible to fasten a camera to the repro column 10.

FIGS. 5 a and 5 b show developments of the solution according to theinvention. This embodiment is characterised by the fact that theflexible basic body is arranged on flexible frames, respectively frameparts 5/4. These flexible frame parts are formed, for example, by aflexible tube which can be angled in very different forms and which hasa sufficient stability so that it can be angled, for example for certainphotographic pictures, into an angled form which then remains during thetaking. Flexible frame parts like that are created for example as tubes,respectively box-like elements, consisting of individual segments. FIG.5 a here shows a trapezoid body which has been produced by bending theframe parts 5/4. In the drawing 5 b the flexible basic body has beenbrought into an S-shaped position which is given through the frame parts5/4.

Although the invention has been described by exact examples which areillustrated in the most extensive detail, it is pointed out that thisserves only for illustration and that the invention is not necessarilylimited to it because alternative embodiments and methods become clearfor experts in view of the disclosure. Accordingly changes can beconsidered which can be made without departing from the contents of thedescribed invention.
